As many predicted, the debut of Windows 7 has prompted a surge in PC sales – for now, at least. During the first week of general availability, Windows 7 boosted computer sales by some 40% year-over-year, according to Morgan Stanley analyst Katheryn Huberty.

The figure is based on NPD sales data, and is partially skewed by consumers holding off purchases. During the two weeks leading up to Windows 7's launch, sales fell 29% and 2% compared to 2008. While computer sales have rebounded (and then some) from that stint, many people – including Microsoft CEO Steve Ballmer – don't expect Windows 7 to have a long term impact on PC sales.

Huberty also dismissed concerns that computer vendors over-shipped ahead of the Windows 7 launch by showing that PC inventory levels are still below average. Did you, or anyone you know, purchase a new computer during the Windows 7 launch week?
